18 Claims.

This invention relates to winding machines of the type which comprise apressure member such as a roll which bears against the surface Moreparticularly the invention relates to the positive separation of thepressure member or roll from the suriace of the windings when the membercarrying the windings is decelerated or stopped. The positive separationis synchronized with the brake or braking action applied to the membercarrying the windings.

In standard machines for winding yarn, fabrics, films, and the like on acarrying member, such as a cylindrical or conical core, it is usuallycustomary to employ a pressure member such as a roll or roller tocompact and smooth out remains constant and consequently the materialbeing wound is rubbed and damaged by the pressure roll.

In cases where both members are'driven, i. e.,

the carrying and pressure members, complicated .devices must be employedto synchronize the revolutions of the same since the peripheral speed ofthe carrying member and the surface speed of the pressure 'roll mustremain the same. Complicated devices are likewise needed in such a caseto synchronize the braking action of the two members in order to avoiddamage to the windings due to friction. V 7

In the winding operation irregularities in the windings very often occurdue to eccentricities, bulges, or bumps that are formed due to, for ex-,ample, overly thick portions in the material being wound. Windingdevices of the prior art have the disadvantage that if a slightdistortion at some part of the-periphery of the winding occurs, such asa bulge, the pressure element is moved outwardly from the axis of thewinding at the position of the bulge and then returns toward the axis ofthe winding at it leaves the bulge causing a bumping of thepressuremember on the surface of the windings each time thebulge iscontacted. -.During high speed winding, the fluctuations of thepressureyelernents that result from hitting one or more of such bulgesabout the periphery, tends to cause chattering or vibration and anunsatisfactory winding results, i. e. one not having a round crosssection. There is also the danger that the bouncing or vibration of thepressure member or roll on the surface of the windings will damage thesame.

Accordingly, it is an object of the present invention to overcome theaforementioned difiiculties and provide a simple means for preventingdamage to the windings during the braking of the member carrying thesame.

Another object of the present invention is to provide a simple andeflicient means for removing the pressure member from the carryingmember surface during the braking of the latter.

Another object of the invention is to provide an apparatus for producinga perfectly round section winding containing windings having a minimumof abraded portions.

Other advantages and objects of the present invention will be obviousfrom the drawing and description thereof hereinafter.

In the drawing, which is intended to be illustrative and not-limitative,

Figure l is a side elevation of one embodiment of the invention,

Figure 2 is a side elevation of another embodiment of the invention,

Figure 3 is a plan view of the snubbing mechanism, and

Figure 4 is a diagrammatic view of an electrical system that may beemployed with the embodiments shown in Figures 1 and 2.

The objects of this invention are in general accomplished by providing arotatably mounted pressure roll which rests against the surface of thepositively driven winding roll. This pressure roll may be made ofaluminum, phenolite, rubber, neoprene, and the like, or its outersurface may be covered with a layer of one of these materials. Thewinding roll is provided with a brake or, if desired, both thewindingand pressure rolls may be provided with brakes.

The pressure roll supporting assembly is movably mounted such that thepressure roll may position when a new winding is started.

The pressure roll is movably mounted on the movable assembly so as to becapable of being removed from the surface of the winding rollindependently of the pressure roll assembly by positive removing meanssuch as a torque motor and cable, solenoids, and the like. In this case,however, the pressure roll is returned to the winding roll surface whenreleasing "the positive removing means. The positive pressii-re rollremoving means and the winding roll braking means are synchronized sothat the pressure roll is removed from the winding rollsurfacesubstantially before the deceleration is --cdriiplete'd andpreferably before the latter begins to 'de'-'- celerate.

The apparatus may be adjusted so that the i pressure roll may beretracted or removed any reasonable distance such as inch, prior tobraking the winding roll.

For a more detailed description of the invention, reference made toFigure lof 'the dravv- -i'ng which depicts one embodimentof theinvention as it is applied in winding yarnon'a warp beam. It should beunderstood that while the invention is described with-respect toitsapplication toa warp ,beamer, this is merely intended to "beillustrative and in 1 no sense "limitative.

The yarn I coming from the creel -(not shown) passes over a guide A,under the hook-like portion of the dropwirfe-switch 4, through openingsin an eye-board 2, -between--the guides B and C which :serve to convergethe various yarns in a plane, then through a-comb -3, over a guide or;mea.s u-ri-r 1g*rol1 4a, and then wound onthe beam 5 "beam is driven bymeans of the belt -6 attached to the power or driving motor 1.

Resting against the surface of the beam is a pressure roll 8, shown inthe raised position, the dotted lines representingth'elowered or normalposition. V The pressure roll-is rotatably "mounted ;on shaft 8a whichis Supported-at either end of the pressure roll by lever arms pivotallyrnounted on shaft-9.

The purpose of -the tog'gle-l inkage l is to swing airmi l 0 m acounter-clockwise-kiirectin While at n'oid supporting frame 22 fastenedto the arm l4, and into the solenoid 23. When the solenoid- '23ise'nergized, the rOd 2| is pulled upward carmachine.

When the "torque motor 24 is started, it rot'a't'es a "gear sector "25in "a "counter-clockwise "di- "rc'tioh. The gear sector 25 is secured toor an integral part or the 1ever '16 I-Divo't'e'd iat Tl.

This normal or non -braking position is attained by ineans of thetension spring "4 3 extending between the 'gear sector 'z's and thebeamer frame.

The armature -rying the 'togglefil-inkage up past its center posi-tion'thus swingingarm I0 in a counter-clockwise direction liftinglp'ressure roll 8 ofi the yarn sur-,' face of the beam. If desired, asimilar solenoid setup maybe employed on the other side of the; When thetoggle linkage moves upward, the tension spring I! is extended. The

When, as previously recited, the torque motor 24 rotates thegear sector25 in a counter-clockwise direction until the sector touches the fixedstop 25a, the link, 28 is moved upwardly thus rotating the shaft 29 andthe spreader 42 thereon in a counter-clockwise direction to the positionshown. The brake shoes are thus pushed together tightly about the brakedrum 3i due to the action of the. compression spring 4|. Prior to thisbraking action, the solenoid has been energized lifting the pressureroll from the yarn surface before the beam has started to slow down. Allthis action takes place in a relatively short period of time thusstopping the beam quickly and efliciently when a break in the yarnoccurs without anyidanger of damageto the yarn on thegbeam. aIrrespective of the pressure roll retracting and beam brakingmechanisms, the lever 10 supporting the pressure roll 8 is rotated in acounterclockwise direction due to the building up of the warp yarn onthe beam. In addition to the lever 10, the arm l4 and sector gear II arealso rotated in a counter-clockwise direction since the toggle linkagewhen in position Ib rigidly connects arms l0 and I4 and arm l4 andsector gear II are locked to shaft 9 and thus fixed with respect to eachother. Thus the entire structure connected to the pressure roll swingsto the left as viewed in Figure l.

When the arm l4 swings to the left, the bar 44 ;pivotally mounted on theend of arm [4 at 45, is also moved to the left through the snubbermechanism 46. The snubber, described hereinafter, will allow the bar 44to move to the left but not to the right. Therefore, as the yarn iswound on the beam, the pressure roll support will rotatecounter-clockwise moving the bar 44 to the left, and should a high spotor bulge come in contact with the pressure roll moving it farther to theleft than the remaining yarn surface on the beam ordinarily would, thesnubber 4B prevents bar 44 from moving back to the right thus in turnpreventing the pressure roll 8 from returning to make contact with thenormal yarn surface on the beam. The pressure roll will not again comein contact with the entire yarn surface on the beam until the overallsurface of the beam has ,reached a radius equal to that of the highspotg; Thus an even and perfectly round section beam is assured.

When a beam has been finished and removed fromthe beamer, it is ofcourse necessary to returnthe pressure roll to the surface of the newunwound beam. This is accomplished by releasing the snubber, themechanism for which is described hereinafter, and rotating the sectorgear H in a clockwise direction by means of the pinion 41 fastened tothe fixed transverse shaft 48. It is to be understood that a like pinionand sector gear may be positioned on the opposite side of the beamer inconnection with a duplicate mechanism attached to the opposite end ofthe pressure roll 8 from that viewed in Figure 1.

' Attached to the beamer frame by means of bearing-like pieces 49 and 50is a rotatable shaft 5i attached to the lower end of which is a bevelgear 52 enmeshed with bevel gear 53 fixed on .shaft 48. At the other endof shaft 5| is a hand wheel 54. The shaft 5| is attached to the oppositeside of the beamer frame from that shown 'i-in Figure 1., When the handwheel 54 is rotated ime, counter-clockwise direction,the shaft 48 and'pinion' 141. are likewise rotated in a counterclockwise direction, duetothe action of the bevel gears 52 and 53, thus moving the pressure rollsupporting structure to the right. In this way, the pressure roll isreturned to its starting position ready for the winding of a new warpbeam. If desired, the shaft 5| may be rotated by means of a motor or thelike, instead of manually. For a description of the snubber 46 and thesnubber releasing means, reference should be made to Figures 1 and 3.The bars 44 extend through the snubber housings 55 which are pivotallymounted on conical pins 55 fastened to supporting members 51, which inturn are mounted on the angle iron 58 mountedtransversely in the beamerframe. The snubber housings are pivotally mounted to allow for theslight up and downward movement imparted to bar 44 as a result of therotation of arms [4 and H about the pivotal point l2. v

Pivotally mounted in the center of the snubber housing 55 on the shaft59 is a one-way friction device or block 60, the underside of which ismade to conform to the shape of bar .44 on which it rests. The bar 44may be any shapebut that illustrated is preferred in which the sides BIand 62 slope inwardly and upwardly. The block is held down tightlyagainst the bar 44 by means of the compression spring 69 which isadjustably mounted on the plate 64 extending transverse of the snubberhousing and fastened to the sides thereof. The tension on the spring isadjusted by means of the screw 65 and lock nut 65. When the bar 44 movesto the left, as viewedin Figure 1, the block 60 is swung about the pivot59 in a clockwise direction against the force of the spring 63, thuspermitting the bar 44 to pass through the snubber housing. When anattempt is made to move the bar 44 to the right, the force is againstthe pivot 59 thus binding the block or snubber 60 and the bar 44 andpreventing any movement of the latter through the snubber housing.Hence, a snubber releasing mechanism i necessary in order to return thepressure roll to its starting position.

The snubber releasing mechanism comprises a steel cable 61 fastened toone side of the beamer frame by means of a tension spring 68 andextending transverse of the beamer over the snubber housings and over apulley 69 fastened to the opposite side of the beamer frame. The cablethen extends down under pulley Ill, along the base of the beamer andunder pulley H, up over pulley 12, and down to a foot pedal 13 where itis fastened. Extending outwardly from the non-pivotal ends of thesnubbers or blocks 50 are pins 14. These pins extend out over thewedge-shaped member 15 fastened to the cable 61. The wedge-shapedmembers 15 slope downwardly from right to left as viewed in Figure 3 andare positioned between the pins 14 and the upper surfaces 16 and ll ofthe snubber housing sides. When the foot pedal 13 is pressed down thecable moves from right to left, as viewed in Figure 3, against theaction of spring 68. The wedges 15 passing under the pins [4 raise thesame thus rotating the snubbers about the pivots 59 and removing themfrom contact with the. bars 44 permitting the movement of the latter ineither direction. When the pressure on the foot pedal is released, thetension spring 68 restores the cable to its starting position thusremoving the Wedges 15 from contact with the pins 14. In order to limitthe movement of the cable and protect the spring, metal stopsla andwere? fastened tome-cable on eitherside of 'the snubberhou'sing.

In Figure 2- them is shown another embodimentof: the invention whereinthe pressure roll: 8 i's' movedawayfrom the yarn surface on the beam bym'eans'of a-cable 8U- fastened at one end tothe eente'r'ioint N- of thetoggle lihkage and extending down around the link H and fastened to apulleyfil on the torque motor 2t. When the pressure roll is against thesurface of the beam, the" toggle linkage is inthe dotted-line position82 with its center slightly above the straight line betweenpivotalpoints" :9 and on arms 14 and 0 respectively, and resting against-thetoggle stopstg'iand 8'4 on arms l4 and Hi. If a yarn l breal z-s -orlthe manual switch isclosed, the torque motor ill-isactuated pulling thecable 80 which inturn pulls the toggle linkage down through the=- centerposition to the position shown thus raising the arm It andthe' pressureroll 8 from the yarn surface on the beam. The toggle linkage actsagainst'the compression spring whioh fastened tothe arm Hi The purposeof the compression spring is to return the pressure roll to thesurfac'eof theyarn' on the beam when the" circuit to the torque motor 24 isbroken. There may be asimilar set up on the otherside or the'beamer'with both cables connected to the onetorque motor. The: gears on thetorque motor are so chosen that the pressure roll lifts off thebeambeforethe brake'is applied to the beam. I -s-i'nce't-he brakingmechanism, snubber, snubber release, etc. are the same in thisembodiment as that shown in Figure l', a description of the same" is notnecessary here and is not shown in Figure 2fo'r the'purposeofsimplicity.
